In article <Pine.BSF.3.91.961009085550.6317A-100000@revelstone.jvm.com> you wrote: : netstat often stalls, sometimes partway through the listing. Sometimes : it will continue after a few seconds, sometimes not. And occasionally it : gives this error : netstat: kvm_read: Bad address : and keeps on going. Is there something wrong here? We're running 2.1.5R Nothing much that you should be worried too much about. When you run netstat it trys to do reversed DNS lookups to turn the IP numbers that are involved in connections into names.. hence the delay. You can use a "netstat -n" to tell netstat not to do these lookups. The kvm_read could be related to these delays. Netstat runs through a linked list of all the connections. One of these connections could die, or more could be added, durring one of your DNS lookups, causing the next bit of the list to disappear. Hence the message.
